CUT NAIL.

SPECIFICATION forming part of Letters Patent No. 423,009, dated March11, 1890.

' Application filed December 26, 1888. Serial No. 294,724. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM WICKER- SHAM, a citizen of the UnitedStates, residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement in Nail-Platesand Cut Nails, of which the following is a specification.

The principal feature in my invention consists of a nail cut from aplate with ridges on its two sides to form the two sides of theprojecting head, and having projections 011 the two edges of said headbelow said ridges on one side by having the chisel-point of theadjoining nail cut from it and on the other side by being cut from thenail-plate with the same angle as the chisel-point of the next nailto-be cut from said sheet, the nails being cut from a wide sheet incolumns, with alternate heads and points at each edge of the columns. Imake these chisel-p0ints at about the angle of sixty degrees, yet theymay be made any desirable angle. I have these chisel-points compressedon each side, making the extreme point thinner than the shankof thenail.

The character and utility of my nail will be more apparent by referenceto my drawings, in which Figure 1 shows a portion ot'a nail-plate,

showing the form of the nails just as they.

would be out from said plate; also giving an edge View of one of thenails; also giving a sectional View of said plate, which is wide enoughfor two columns of nails. Fig. 2 gives a side and edge view of my nailon a large scale.

A is the nail-plate.

a a a are the ridges which make the two parts of the head on the twosides of the nail.

A is a cross-section of said nail-plate;

b b b show the chisel-points of the nails.

0 c c are the parts of the heads below the said ridges a.

d d d are the parts of the ridge after the nails are cut on each side ofthe head. i

e e are the two sides of the chisel-point, which are compressed to lessthickness than the shank f of the nail. These chisel-points are-cut fromthe two edges of that part of the head below the said ridges a, givingto these parts of the edges of the head the same angle as the edges ofthe chisel-point have to the edges of the shank of the nail.

It will be seen by reference to the drawings that the two sides of thepoint at e e are a little compressed and thinner at the extreme pointthan the shank of the nail. .One side at e is compressed by the act ofcutting the nail from the sheet, and I have the cutter so formed as tocompress the other side at e to an equal amount, and this equality ofcompression on the two sides of the point insures the nail always todrive straight through the wood, and itgives the point end of the nail agreater holding power than it would have if the two sides of the pointwere not so compressed.

The chisel-point with the ordinary head of a nail is not new, as shownby the reference in the case of Staceys patent, No.166,821,

August 17, 1875; but this was a mere ordinarychisel-point; but what Iclaim as new is the ordinary head and a head made partly of ridgesrolled on the nail-plate and partly by cutting, combined with a peculiarchisel-point, a chisel-point cut to a sharp angle on its edges 1) b, butalso compressed on its two sides e 9, making the nail greatly morevaluable.

Having described my nail and the plate from which it is cut, I willstate my claim as follows:

1. A cut nail having a head formed of projections d d and c c and achisel-point b, with compressions e e on its two sides, as described,and for the purpose set forth.

2. A cut nail in which the projections of its head have the two sides 01(1, formed of ridges a a, rolled on the nail-plate, and its two edges 0'0 formed by cutting, and a chiselpoint I), having compressions e e onits two sides, as described, and for the purpose set forth.
